Sys * Stim 226 Instruction Manual— Rev. D_11/09 Section 3—Installation 3.1 Installation Instructions 1. Connect the line cord to the bottom of the Sys * Stim 226. (See Figure 3.1) 2. Plug the line cord into a grounded wall outlet that has 115 VAC, 50/60 Hz. Your power supply must match the voltage requirements listed on the serial number label of your device.
Mettler Electronics Corp.— Rev. D_11/09 4.1 A Note About Electrodes To ensure safe operation of the Sys*Stim 226, follow the recommendations listed below: 1. We strongly encourage careful maintenance of the electrode system. This includes the lead wires as well as the pads themselves. Worn cables and/or poor pads (or the wrong sized pads) can have a significant impact upon treatment results.
Review precautions, contraindications and side effects/adverse reactions listed in Section 5. b) Use Mettler Electronics electrodes to ensure safe and effective operation. c) Verify connection of the line cord to a grounded wall receptacle and the Sys * Stim 226.

Sys * Stim 226 Instruction Manual— Rev. D_11/09 adjust intensity to the desired level. Then press again to initiate the treatment cycle. The intensity may be adjusted only during the “On” part of the “Surge” cycle. • In the “Reciprocation” mode, The Sys * Stim 226 will prompt you to adjust the intensity in Channel 1.
Mettler Electronics Corp.— Rev. D_11/09 • In the “Two Timer” mode, pressing the lower button stops treatment in both channels. 13. In the “Two Timer” mode, use this button to either program or view the time remaining for the other channel.
Sys * Stim 226 Instruction Manual— Rev. D_11/09 3. Quadpolar electrode application technique Quadpolar techniques should be used with the “Interferential” waveform. The electrodes from Channel 1 are placed diagonally from each other. While the electrodes from Channel 2 are placed diagonally across from each other to form an “X”...
Mettler Electronics Corp.— Rev. D_11/09 5. Monopolar electrode application techniques Monopolar techniques may be used with the “Premodulated”, “Medium Frequency” and “Biphasic” waveforms. The smaller, active, electrode (black and negative) is placed over the muscle motor point. In treatments designed to relieve pain, the Figure 4.5—Monopolar...
Application of simultaneous therapeutic ultrasound and electrical neuromuscular stimulation can be accomplished using the pulsed waveforms from the Sys * Stim 226 with a Sonicator therapeutic ultrasound unit from Mettler Electronics Corp. In this technique, the ultrasound applicator delivers the ultrasonic energy and becomes the active electrode for muscle stimulation.
Sys * Stim 226 Instruction Manual— Rev. D_11/09 Section 5— Indications, Contraindications, Precautions and Adverse Reactions 5.1 Indications The application of pulsating electric currents to the body via electrodes elicits responses from nerves, which conduct pain sensation and muscle contraction information. Stimulation of sensory fibers will help block pain while the stimulation of motor fibers will generate pulsatile contractions of the muscle groups innervated by the nerves being stimulated.
Mettler Electronics Corp.— Rev. D_11/09 7. Fresh fractures should not be stimulated in order to avoid unwanted motion. 8. Do not apply stimulation transcerebrally (through the head). 9. Do not use on cancer patients. 10. Stimulation should not be applied immediately following trauma or to tissues susceptible to hemorrhage.
Sys * Stim 226 Instruction Manual— Rev. D_11/09 5. Avoid placing electrodes directly over open wounds since current density tends to concentrate in these areas. 6. Use extreme caution when treating desensitized areas or on patients who may not be able to report discomfort or pain.
Sys * Stim 226 Instruction Manual— Rev. D_11/09 Section 6—Maintenance and Troubleshooting 6.1 Cleaning the Sys * Stim 226 1. The Sys * Stim 226 can be wiped off with a damp cloth. The power cord should be disconnected from the unit before this is done. In the case of stubborn dirt a gentle household cleaner can be sprayed on the cloth and then wiped on the unit.
